Fiscal deficit: meaning, formula and related deficits
On this page
The fiscal deficit is the gap between the government's total expenditure and its total receipts excluding borrowings. In other words, it is the amount the government has to borrow in a year. It is normally expressed as a percentage of GDP so that countries and years can be compared.
Fiscal deficit = total expenditure − (revenue receipts + non-debt capital receipts)
The three related deficits
| Deficit | Formula | What it tells you |
|---|---|---|
| Revenue deficit | Revenue expenditure − revenue receipts | Whether day-to-day spending is covered by regular income |
| Fiscal deficit | Total expenditure − total receipts excluding borrowing | Total borrowing need |
| Primary deficit | Fiscal deficit − interest payments | Borrowing need if past debt had no interest |
Worked example (hypothetical, in ₹ lakh crore)
Revenue receipts are 30, non-debt capital receipts 3, revenue expenditure 40 and capital expenditure 8.
- Total expenditure = 40 + 8 = 48; receipts excluding borrowing = 30 + 3 = 33
- Fiscal deficit = 48 − 33 = 15
- Revenue deficit = 40 − 30 = 10
- If interest payments are 10, primary deficit = 15 − 10 = 5
- If GDP is 300, the fiscal deficit is 15 ÷ 300 = 5% of GDP
A revenue deficit of 10 against a fiscal deficit of 15 would be unhealthy, because most borrowing would be funding current consumption and not assets.
How the deficit is financed
The government borrows by issuing treasury bills and government securities to banks, insurers and other investors. The more it borrows, the more supply of bonds in the market, which can push up yields. This is also why the RBI's open market operations matter for borrowing costs.
The legal anchor
The Fiscal Responsibility and Budget Management (FRBM) Act, 2003 sets targets to bring the deficit down. The Union Budget 2025-26 announced a shift towards a debt-to-GDP anchor in coming years, so look at the latest budget documents at indiabudget.gov.in for the target currently in force.
How bank exams ask about it
Questions test the formula, the difference between the three deficits, and what a fiscal deficit means in plain terms (the borrowing need). Statement questions say "fiscal deficit = revenue deficit + capital expenditure − non-debt capital receipts" and expect you to recognise it. Note it in the economy block of banking awareness.
Frequently asked questions
Is a fiscal deficit always bad?
Not necessarily. Borrowing to build roads or ports can raise future income. The concern is persistent borrowing to meet routine spending.
Where does the number appear?
In the Budget at a Glance and the Fiscal Policy Strategy Statement on the Union Budget website.
